Re: Stus-List C$C 32
Bob - Check with your local phrf organization or sail maker. This is the formula I was given for spin sail area in sqft. See if it makes sense for you. PHRF Rule ((SLU+SLE) x (4*SMG + SF))/12 Slu = spin luff Sle = spin leach Smg = spin mid-girth Sf = spin foot From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Michael Clow via CnC-List Sent: Thursday, May 01, 2014 4:44 AM To: sam.c.sal...@gmail.com; cnc-list@cnc-list.com Subject: Re: Stus-List C$C 32 My symmetrical chute was made specifically for racing by Al Declercq in Metro Detroit so it would be the maximum legal size.

Re: Stus-List C$C 32
Bob, it looks like you're getting some good answers from others on the list. Out of interest, why do you need the area? Is it to size handling gear / lines? Mauri pro has the formulae below, but if you have a running spinnaker with broad shoulders it will be bigger than a reaching spinnaker with a tighter luff / smaller shoulders. It calculates 861 / 939 sqft for cruising / racing spinnakers respectively for the CC 32. In comparison, it calculates a racing spinnaker at 1130 sqft for the 35-3, but my reaching sail measures at 965 sqft, so you need to take the area with a pinch of salt. Tim Mojito CC 35-3 Branford, CT The following formulas will give you approximate sail areas: Mainsail = (P x E) / 1.8 (1.6 for racing profile mainsails) 155% Genoa = (( J x I ) / 2) x 1.65 135% Genoa = (( J x I ) / 2) x 1.44 100% Jib = ( I x J ) / 2 Racing Symmetrical Spinnaker = 1.8 x J x I Racing Asymmetrical Spinnaker = 1.8 x J x I Cruising Asymmetrical Spinnaker = 1.65 x J x I On Wed, Apr 30, 2014 at 9:09 PM, via CnC-List cnc-list@cnc-list.com wrote: Can Any one tell me the sail area of a Spinnaker for a CC 32, or the fomula to get the area?

Re: Stus-List C$C 32
The square footage is a function of how the sail is built. My spinnaker has high 'shoulders' and is 24 feet across at the foot and about 35 feet tall. But I could get another with the same external measurements but cut in a more triangle configuration (no high and wide shoulders) and have a lot less cloth. That is probably why you don't see spinnaker square footage on sailboat specs.
